Been running a swz 48" hydro all summer, for the last couple of weeks every single time I disengage the clutch it squeals horribly. I brought it in to the shop (where i bought it) and had them check it out. The mechanic told me it was because I had put high lift blades on it. Is this true? Being young (19) people tend to think they can dick me around! I laid down $5,300 cash last April for this mower and a bag. I have been treated very poorly by these guys on other occasions. If I would have done the right thing and bought the 48tthp for $800 more I wouldnt have this problem, because those guys are good honest people, but it would have taken around ten days and I still wasnt sure on the ECS. Anyways I need to get the clutched fixed, because its sort of embarrasing around customers. Any advice on what to say to these guys if it isnt the high lift blades.
